The screenshot is T-Mo HSPA+, he is doing the T-Mobile version of SGS2 review.
I really hope you are right. But there is a lot of evidence pointing in the other direction:
http://www.androidcentral.com/notion-ink-ceo-confirms-ice-cream-sandwich-oct-omap-reference-platform-says-adam-will-update-nov http://androidandme.com/2011/08/news/tis-omap4-pretty-much-confirmed-as-lead-platform-for-ice-cream-sandwich/I hope it's all bad rumors but I think I remember news of Google choosing OMAP4 as the reference platform.
Why Google would up the resolution but still use the same GPU as for the Nexus S? Maybe they optimized the OS significantly which would be very good news but the GPU is still a weakness. As much as I don't like it, it does make sense from Google's point of view to ensure ICS can ran on lower end devices. Even though some are still waiting for Gingerbread update.
We wait and see I guess.
Anand has a nice article on the S4 lineup:

These things are fast, Qualcomm's version of the A15 Cortex is 30%-50% faster than current A9's clock for clock so even more overhead there with the 28nmm silicon, Adreno 225 said to be 50% faster than the 220. Those combined should make for a next gen performance. These will make it into phones in H1 2012. Both Nvidia and Qualcomm have published the whitepapers, indicating they are ready for production but all waiting for the die shrink. I am sure the next Evo will have one of these.
H2 is where it gets really interesting though

During summer and fall, OMAP5, A6, Exynos 4212 and Kal-El+ (28nm) are all expected to make into phones and tablets and Qualcomm is saving it's best for H2 2012. MSM8974 is a brand new architecture, quad core @2.5 GHz with Adreno 320. Can't wait to see how they all compare to each other. It's all shaping up for a next gen storm storn in summer/fall 2012 followed by clock bumps and rehashes, it will be a while before new architecture replaces A15.
The problem we T-MO users have is to match these new SoC's with our preferred phone makers, then with our preferred OS and finally, with out preferred carrier, T-Mobile. In this process of elimination, 5 out 6 good phones we want we can't have because the above process has made out of reach for us with at least one factor.
Even when we do get lucky with that selection, it takes a very long wait to get our hands on such phone.
We both know the SGS2 is a really good phone but here in the US, they are delayed by 6 months and that's a lot of time in the mobile industry.
